IMPROVEMENT IN REVOLVQNG FIRE-ARMS.

Specification forming partpof Letters Patent No. 39,409, dated August 4, 1563.

To all whom it may concern:

ford Terrace, TrinitySquare, Southwark, Surrey county, England, have invented certain new and useful Improvements'in Revolvers; and I hereby declare that the following is a full, clear, and exact description of the same. This invention relates to an improved constrnction and arrangement of that class of firearms known as revolvers, whereby greater tion to make an extra bent in the tumbler and to modify the form of the hook. The

- upper strap and the barrel are forged in one piece, and the lower portionot' the frame and undenstrap are connected or jointed to the barrel itself .in a peculiar manner. hereinafter described. V

Figure 1 of the annexed sheet of drawings represents a full-sized elevation of a revolverpistol constructed according to this invention.

' Fig. 2 is a'sep'arate detail, showing the mode of connecting the barrel with the frame and stock, theparts being shown separated. Fig. 3 is an internal view of the lock and trigger,

showing the manner of their connection and the modifications introduced into the action. Fig.4is a separate detailof the lever-rammer, and Fig.5 is an end elevation ofthe revolving chamber detached.

'Ais 'the'ordinary gun-lock, d'etached from the body or frame, which admits of the'action' be- .ing completely inclosed within the stock, and consequently the dan gerof pieces ofdischarged caps or other matters falling into and deranging the;action of the lock is entirely obviated. The lock is detached from the body or frame, and thecoekr B works outside of the lock-plate in the ordinary mannernb'nt I. lay no claim to this side cock when not combinedwith a detached lock.

G is the usual safety-bolt.

Be it known that I, JAMES KERR, of 17 Bed- The rotation of the cylinder D is effected by the following means, combined with the ordinary gun-lock: The ordinary lev er,'E, (shown in red lines in Fig. 3) is jointed to therear pqrtion of the trigger F, which turns on the fixed stud-center f, and the point of this lever acts upon the ratchet-teeth formed on the base of the cylinder shown in Fig. 5, which arrangement is common to most revolving hire-arms, and forms no part of my invention when not combined with orapplied to an ordinary gunlock. A stud or hook, 5!, Fig. 3, is formed-on or inserted in the tumbler G of the look. This stud or hook engages with a stud, h, on the upper end of the link-piece h, (shown in edge view at Fig. 3 which link is jointed to the trigger by the same pin which serves to connect-the lever E. The cooking of the look by pulling back the hammer will obviously cause the stud g to raise the trigger through the introduction of the link It, and consequently the lever E will be simultaneously raised and rotate the cylinder by acting against one of the ratchet teeth in the base, while at the same time a projection, f, on the trigger will be brought into a recess in the cylinder, thereby locking itin the proper position for discharge. The single pulling action-namely, the power of cocking and firing by simplypulling the Y trigger-is easily obtained in this look by simply having an extra bent or notch, a,made in the fore part of the tumbler, and causing the external upper end of the link h to take into.

spring 1).,- Thelink h, in'rising, forcesback the hammer,a||d isthen thrown off or'releazsed fromthe bent by the pressure against it of the fore par tof the tumbler as it comes round, whereupoh-the. hammer-falls and strikes the cap.

The barrel. H, Fig. 2, of thepistol isforged' vseparately or apart'from the body or frame, and is connecteih-therewith in the following manner: The frame I and Iowerstrap, K, are

connected at L by a square tongue itnd'slot and pin to that part of the barrel'throughwhich.

the rammingplung'er M passes into the chamber, while th'el'ninder part of the barrel forms the upper strap, N. This strap is let into the upper surface of the stock and drops into a re- 'cess, 0, formed in the body or frame, the two ;straps and stock beingfirmly secured together by ascrew-pin passing through the upper strap and stock and entering the under strap, so that the stock is firmly griped between the two straps. The-upper strap and the frame are still furtherheld together by another screw at. c, and also by the cylinder-rod P, which passes e through the corresponding openings, 0? d, made for that purpose in the upper strap and frame, respectively. 7

My improved lever-action for the rammingplunger shown at Fig. at consists in having a lever, Q, working on a fixed fulcrum, R, and

' having a curved slot made therein, in which' slot works the connecting-pin of the rammingplunger M.

I lay no claim to any of the parts separatei y, but claim only- 1. .The combination of the lever E, trigger F, link h,stnd h, hook g, and extra bent awith the ordinary tumbler and sear, these parts constituting a lock detached from the body or frame, as hereinbefore described, and illus trated by my drawings.

2. The adaptation and use to andin revolving fire-arms of the ordinary gun and pistol lock detached from the body or frame, as here- 'inbcfore described.

3. The peculiar mode hereiubefore described of connecting the barrel with the frame and stock when such barrel is forged apart fromthe body or frame.
